Gear-driven transmission: This is the most common type of transmission used in self-propelled mowers. It consists of a series of gears that transfer power from the engine to the wheels. The gears are engaged and disengaged using a lever or knob on the mower's handlebars.
Belt-driven transmission: This type of transmission uses a belt to transfer power from the engine to the wheels. The belt is tensioned using a spring or pulley system.
Hydrostatic transmission: This type of transmission uses hydraulic fluid to transfer power from the engine to the wheels. The fluid is pressurized by a pump and then directed to a hydraulic motor, which drives the wheels.
The type of transmission used in a self-propelled mower will depend on the size and power of the mower. Gear-driven transmissions are typically used on smaller mowers, while belt-driven and hydrostatic transmissions are used on larger mowers.
Self-propelled mowers offer a number of advantages over walk-behind mowers. They are easier to use, especially for people who have difficulty pushing a mower. They can also mow larger areas more quickly and efficiently.
